The HUB-ee is a type of robot servo but designed for wheels, in fact it is a wheel, but it is also a motor, a sensor and a motor controller. What’s that? Did we just blow your mind?

When you want to add wheels to your robot you would normally start with a whole collection of parts: The motor and gearbox, a motor driver board, and maybe some sensors for measuring wheel speed and a controller to count revolutions or provide closed loop speed control. Well, the folks over at Creative Robotics thought it would be handy if you could just buy a wheel that had all of those things built in, so they designed HUB-ee - just bolt it onto a chassis, apply power and away you go!

The HUB-ee is easy to mount, too! There are two threaded inserts for M3 bolts built in, there’s also a right angle bracket included for situations when you can’t go horizontal into the chassis. The mounting holes are even LEGO® lug compatible!! HUB-ee uses Micro-MaTch connectors to keep electrical connections tight and easily changed, check out the related items for mating connectors.

Core Skill: Robotics

This skill concerns mechanical and robotics knowledge. You may need to know how mechanical parts interact, how motors work, or how to use motor drivers and controllers.

2Robotics

Skill Level: Rookie - You will be required to know some basics about motors, basic motor drivers and how simple robotic motion can be accomplished.

Core Skill: DIY

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.

1DIY

Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

1Electrical Prototyping

Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

Customer Comments

Cool… but when it costs 85.5 just to get two wheels spinning i’m tempted to just build my own setup for half the cost if i’m building a robot. However, this could be a useful for some of the Lego Teams I mentor.
